Two years after opening, Progress West HealthCare Center in O'Fallon, MO, will expand with a new medical office building that will bring more general physicians and specialists to the facility. Construction of the 60,000-square-foot office building is expected to be completed by the second quarter of 2010. The new medical facility at the 72-bed hospital will provide additional outpatient services such as therapy, cardiac care, and imaging, officials said.
